Patent FI-20060721-A (FI)
Inventor: CHEN TAO
IPC: H04J13/00
Filed: 2006-08-10
Abstract: In a method for efficient retransmission of data, symbol accumulation is used to retransmit a packet received in error at a lower energy-per-bit level concurrently in the same frame with a new packet. The destination device receives the data transmission and retransmission, demodulates the signal, and separates the received data into the new and retransmitted packet. The destination device then accumulates the energy of the retransmitted packet with the energy already accumulated for the packet received in error and decodes the accumulated packet. The accumulation of the additional energy provided by the subsequent retransmissions improves the probability of a correct decoding. The throughput rate can be improved since the packet received in error is retransmitted concurrently with the transmission of the new data packet. The capacity is maximized since the retransmission of the packet received in error is at a lower energy level than that of the new packet. <??>The method includes puncturing the code symbols of a data packet for transmission in accordance with a first puncturing pattern. If decoding of the punctured transmitted packet of data is unsuccessful, a negative acknowledgement is received at the source device and the code symbols of the data packet are then punctured in accordance with a second pattern for transmission in response to the receipt of the negative acknowledgement. <IMAGE>

IPC: D21C9/10
Filed: 2010-02-02
Abstract: The present invention relates to a method of controlling filtrate flows and storing of filtrates of a fibre line in a pulp mill. In the method, the fluctuations in the amount of pulp in the pulp storage tank (3, 8, 17, 37) are not compensated by a separate filtrate storage tank, but the aim is to maintain the amount of filtrate in the pulp storage tank (3, 8, 17, 37) steady. When the amount of pulp changes, it is not that much the volume of the pulp in the tank (3, 8, 17) that will be changed, but the average consistency of the pulp in the tank.

Patent GB-1020655-A (GB)
Abstract: 1,020,655. Valves. S. H. LEGGITT CO. Sept. 25, 1964 [June 10, 1964], No. 39122/64. Heading F2V. [Also in Division G3] A control device providing a pulsating flow of gas consists of a block 26, Fig. 1, of metal or clear plastic embodying a U-shaped passage 13 with an inlet 14 and an outlet 16, the limbs of which passage are interconnected by a transfer passage 17 having an inlet 19 that is disposed below its outlet, the intermediate part 18 of the passage 17 being below the inlet 19 and outlet 21. A liquid 22, e.g. mercury fills the passages 13, 17 to a level L and control means, such as an orifice 36 and a valve 23, are provided in the passage 13. Screens 62 are disposed in the gas inlet and outlet 14, 16 to prevent the passage of liquid therethrough. When the gas pressure in the inlet 14 is greater than that in the outlet 16 the liquid level in the inlet sides of passages 13, 17 will fall with a consequent rise in the level in the outlet sides thereof; the movement in the passage 13 is restricted by the orifice 36 and valve 23 so that eventually the passage 17 is emptied into the passage 13 and gas flows from the inlet 14 to the outlet 16. The resulting pressure equalisation between the latter, results in the liquid flowing back through the orifice and valve, the setting of which will determine the time of gas flow, to refill the passage 17 via its inlet 19. Gas control valves may be provided in the inlet 14 and outlet 16 and the valve 23 may be dispensed with. The apparatus may be constructed from stainless steel, copper or glass tubing and the orifice is formed in a plug member. The screens are replaced by porous plugs, e.g. of sintered stainless steel.  In another form, the U-shaped passage need not include any restriction or valve whilst the outlet portion of the passage is enlarged above the directed liquid level to constitute a reservoir. In a further form, the device consists of a closed loop 91 (Fig. 4, not shown), having an inlet 96 and an outlet 98 each with a sintered stainless-steel plug 101, the upper and lower parts of the loop defining transfer and return passages, respectively. Gas at the inlet forms a bubble and separates a quantity of liquid 102 from the main body thereof 22c and forces it past the outlet to allow the passage of gas through the outlet; the gas pressure is then equal on both surfaces of the liquid column and the liquid returns to the position shown to close-off the gas flow. In a final form, the device is constructed as a pair of telescoped and U-shaped tubes 111, 112 (Fig. 5, not shown) separated by spacers 113 with restricted openings 114 therethrough. Liquid fills both tubes to a level Ld. The openings 114 restrict the flow of liquid through the  tube 112 whereby gas at the inlet 118 8 forces liquid out of the tube 111 and then flows to the outlet 119; the openings 114 allow back flow of the liquid from the output side when the gas pressure is the same on both end faces of the liquid.

Abstract: 1,048,604. Photo-electric control of focusing. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 23, 1964 [April 26, 1963], No. 16870/64. Heading H4D. In an arrangement determining the distance of an object, particularly as applied to the photo-electric control of focusing of a photographic camera, a first Wheatstone bridge I, Fig. 1 (not shown), incorporates photo-sensitive resistors 3, 4 and a second bridge II, connected as shown to bridge I, incorporates photosensitive resistors 7, 8, a D.C. voltage being applied between terminals 1, 2. An output voltage appears across terminals 11, 12 only when photo-sensitive resistors 7, 8 are unequally illuminated. The pairs of photo-sensitive resistors are displaced longitudinally with respect to the object, Fig. 2 (not shown), and it is demonstrated that the output voltage from bridge II depends only on the position of gap 19 relative to the object, Fig. 3 (not shown). In the camera a zero output voltage from bridge II corresponds to a sharp image on the photographic film: a prism 44, Fig. 4 (not shown), directs part of the incident light to viewer 43 and part to the photo-sensitive resistors. The output of bridge II is fed to a motor 45 thereby moving lens 41 for correct focus. To increase contrast the photo-resistor system is arranged to reciprocate transverse to the optical axis; adjustment to " left-right " or " upper-tolower " contrast may be effected by making the photo-resistor system rotatable about the optical axis. Spurious bridge balance can thereby be avoided. An alternative physical arrangement of photo-resistors 3, 4 is described, Fig. 5 (not shown), utilizing diffusing plates, e.g. of frosted glass.

Abstract: 1,094,813. Variable-speed friction gear; torque amplifiers. CONTRAVES A.G. March 4, 1965 [March 19, 1964]. No. 9333/6.5. Headings F2D and F2X. In a torque amplifier comprising a constant speed hollow drive shaft 1 driving a coaxial output shaft 4 through a reversible steplessly variable speed gear in which balls 5 are engaged by driving and driven members 2, 3 secured on the shafts 1, 4 respectively, the angular position of the output shaft follows, with a small delay, the angular position of a control shaft 7 passing coaxially through the drive-shaft 1 and in screw engagement with the output shaft 4. By virtue of this screw engagement, rotation of the control shaft 7 moves it axially so that a rack 70 thereon turns cages 8, carrying idler rollers 6, in a fixed block housing the balls 5, to control in known manner the axes of rotation of the balls 5, and hence to change the gear ratio. Turning the shaft 7 to cause axial movement from the neutral position shown shifts the variable speed gear out of neutral to turn the output shaft 4 in the same sense as the shaft 7. This tends to return the control shaft 7 to its neutral position, so that turning the shaft 7 through a given angle causes turning of the shaft 4 through the same angle. Continuous rotation of shaft 7 causes continuous rotation, at the same speed, of the shaft 4.

Abstract: 1,225,872. Induction flowmeters. GEORGE KENT Ltd. March 6, 1969 [March 7, 1968], No.11173/68. Heading G1N. In an induction flowmeter, each of a pair of pipes 1, 2, carries a different one of a pair of fluid-flows, the pipes being arranged to lie in adjacent parallel positions in the magnetic field from a pair of coils 4, 5, and the output potentials from the electrode pairs 8, 9, and 10, 11, being coupled through respective transformers 12, 14, so that the resultant potential at a converter, 15, represents the sum or difference as required of the flow speeds. In an alternative embodiment, Fig.2 a first fluid flows through a pipe 21, having an insulating portion 22, inside which pipe is another 24 of smaller cross-sectional area having curved lengths 25 which extend through the wall of the pipe 21, and a porous sock 26 connected between the curved lengths 25. A second fluid flows through the pipe 24 in a direction opposed to that of the first fluid, if the difference between the flow rates is required. The sock may be of a porous ceramic or a fabric stretched over a supporting frame. The rest of the flowmeter is as above. In a modification of the apparatus of Fig. 2 where mixing of the two flows is not desired, the sock must be of a non-porous material having a conductivity close to that of the fluids.

Abstract: 1,227,316. High lift flaps. HAWKER SIDDELEY AVIATION Ltd. 13 May, 1968 [16 May, 1967], No. 22778/67. Heading B7G. A high lift flap assembly along the trailing edge of each wing 13 comprises a main flap 14, which can be moved from a stowed position (Fig. 3, not shown) to rearwardly extended and downwardly deflected positions (Figs. 4, 5, not shown), and a tab 15 which is aligned with the wing and has its nose 16 close against the flap 14 when the flap is retracted but moves to a position apart from the flap to form a slot 17 and is downwardly deflected from the flap when the flap is fully extended. Rollers 18, 19 run in the guide channels 22, 23 in the wing 13; an extension of the pin 20 beyond the rollers 18 is received in a special link 25 forming part of a chain 26 trained around the sprockets 27, 28, and operation of the chain alters the position of the flap 14. Double-armed levers 29 have an upper arm 30 having a pin 31 moving in the guide channel 23, and a lower arm 33 pivotally connected to a push-pull rod 35 carrying a fixed sleeve 36 with helical slots 37 engaging the pins 38, which are part of the mounting 39 on the flap 14. Full extension of the flap causes the pin 31 to meet the end (not shown) of the guide channel 23 and hence endwise movement of the rod 35, the sleeve 36 also causing the rod to rotate about its longitudinal axis. An extension 40 is attached to the rod 35 and is set at an angle in the horizontal plane to the main part of 35; the extension terminates in a ball end (41), Figs. 3, 5 (not shown), which moves in a horizontal transverse channel 42 in the tab, hence endwise movement of the rod 35 causes rearward and downward deflection of the tab 15.
